THOMAS LUND, OF BEVERLY, MASSACHUSETTS, AS SIGNOR UNITED SHOE MACHINERY CORPORATION, OF PATERSOH, NEW JERSEY, A CORPORATION or new JERSEY.

Application filed December 27, 1919 which the following description in connec tion with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. i

This invention relates to heel building machines and more particularly to that type of such machines whereby a series of heel litts died. out of leather, or other character of sheetmaterial, are assembled and formed into a heel.

in the commercial manufacture of boot and shoe heels it is now a common practice to manually assemble a number of heel hits in a heel form and secure them together by driving one or more fastenin s into the pile; The limited production incident to this practice has led to the developmentof full automatic heel. building machines, which,

while answering the requirements: of the larger and more extensive. factories, have not been economically applicable 'to the building; oi heels in the average manutacturing plant. As an oiiitgrowth of this condition a heel building machine has been de veloped to respond to the demands of the average factory by. making the machine semi-automatic, a term that serves well to identity that type o't heel building machine where the heel li'lt-s are taken from a source of supply, pasted and assembled into a heel pile automatically and then secured together by a manually cont-rolled :lastening insertconstructed and operated thanthe full automatic machines and their productive capacity as compared with the manual assem hly ot the heel llfFtSllllflQI' the old practice is greatly increaseiil, and one of the objects (it the present invention is to provide a machine ot the so-called semi-automatic type which will be simple in construction and etitective in its operative capacity for increased production. y

In antoirnatically assembling the heel lifts to?! treatment in the heel form in machines HEEL-BUILDING MACHINE.

Serial No. 347,740.

of this general type the lifts are piled up one on top of another until the desired number of lifts have been accumulated to com: plete the heel pile, and various means have heretofore been suggested for this purpose. In some suggest-ed instances, the heel lifts have been moved from a source of supply onto other partially formed heelpiles and an intermittent or step movement has been given the partially formed piles after each delivery of a lift thereto until the comple tion of the leading pile of the series which .has then been delivered to the nailing mecha- In other cases the htts have been nism. placed upon a support triiim which they have i been delivered to partially termed heel piles by an intermittently moving assembling mechanism. in still other suggested constructions the heel lifts have been delivered to a carrier having a uni-directional movement for serially delivering the llfts to the forms.

With respect to this feature, the present invention differs from all the prior suggcse tions and is characterized .by lift supports arranged in stepped relation, and automatic means for successively advancing the hits from a higher stepped support onto a lift on the next lower stepped supportby an assembling mechanism which is auton'iatically moved the .t'ulldistance of the line of supports, the effect being to gather theser es of lifts on the stepped supports into a pile -by a single movement of the assembling mechanism.

it is now the common practice to supply tacting surfaces ot the lifts when they are moved from the source t supply, to be piled. The adhesive applied while in a (liquid or semi-liquid condition. and usually gums up the various parts of the machine, a fact which becomes particularly observ able when the pile of lifts aresubjected to pressure in the heel form. The present invention aims among other things, toover come this ohgiectionaltile condition incident to l CD from their stepped supports and progresa quick drying adhesive or glue to the con the application of a liquid adhesive to the lifts while they are being built into a heel, and another important feature of the invention consists in supplying heel liits which have been previously gummed and dried. and moistening or tempering the gummed surface as the lifts are moved from the source of supply to assembling position. Since the lifts are delivered to stepped lift supports the moistening means, which conveniently formed as pad, may have stepped portions to contact with tne gummed surface of the lifts as they move towards the stepped supports. I

fWhen the heel litts have been formed into a heel pile they are to be secured together by one or more tastenings or nails driven into the lifts while the pile oft lifts are under pressure in the heel form. In the present invention the heel lifts are automatically assembled into a pile from the stepped lift supports. and a further importai'n'; feature of the invention in this respect consists in moving the completely formed heel pile into the heel term for the action ot the pressure members and nailing instruments.

} In effecting this movement of the com pletely formed heel pile into the heel form, is des' able to obviate, as tar as possible. any disturbance of the piled lifts relative to each other. Another important teatur of the invention, therefore consists in a heel form having a heel j aw or clamp which is opened to admit the heel pile as is vanced by the assembling; mechanism and is then closed to hold the heel pile for the pressing and nailing operation. During the transfer of the heel pile to the heel form by the assembling mechanism, operation of the pressing and nailinn" mechanism should be prevented. otherwise injury to the mecha nism. is liable to result. A still. turt ier ihature ot the invention. therefore. consists of means connected to the assembliing mechanism which is rendered eilfective to prevent operation ot the pressing; or nailing mechanism dining the operation ot the assembling; mechanism.

Other novel features and new combinations of parts in addition to the above will hereinafter he described in connection with the accompanying drawing. which, while showing one eood practical form of the invention, are not. however, to be understood as limiting the invention to the details disclosed. except as pointed out by the claims.

The machine me may he of any usual or appropriate character for supporting the operating parts and herein illustrated comprises the table or support 1 with which is associated the heel lift assembling mechanism and the frame 2- oonnected to the table 1 and adapted to support the operatin parts of the pressure and nailing; mechanisms. The combined frame work may he a 3pr opriately supported from suitable base members. Mountedin bearings 3 on the machine frame is the driving shaft 4% which may be continuously driven from a suitable source oi? power through the driving member 5 which may be constituted a driving pulley to receive motion from a" line shaft through belting connection. as usual. Loosely mount ed on the drive sha it 4t is the sleeve 6 carrying the worm 7 which meshes with a worm wheel 8 men ted on the actuating shaft 9 for the heel h: t assembling" mechanism. The sleeve 6 carrying: the worm '7 is adapted to be operatively connected at times to the drive shaft 4: through a clutch connection hich heroin shown as a clutch oi the Horton type. This clutch. as indicated in 4i; and 5. is provided with the op 'xosite stop lugs 10 and ll wh ch are adapted to cooperate with the swinging dogs 12 and '13. the construction bong; such that when either ot the dogs 12 or 13 is in its stoppingposition'for engagement by one of the lugs ot the Hortonclutch. the worm sleeve 6 will be freed from its operative connection with the drive shaft. and when both dogs 12 and 13 are withdrawn 'troms engagement with the lugs 10 and. 11. as indicated. in Fig. 4c. the worm sleeve 6 will be operatively engaged with the drive shat't and. be rotated thereby to effect rotation. of the actuating shaft 9.

The actuating shaft 9 may he carried in suitable hearings in the machine frame and extends transversely of the frame. as indicated in Fig; 2. The shaft- 9 carries the sprocket wheel 14:. Mounted in a suitable bearing 16 opposite the sprocket wheel 14 is idler sprocket 15. A sprocket chain '17 exteni-ls about the sprockets l4- and if) and is :mtuated from. the shaft 9, the construction being such that when the shaft 9 is rotated through the means hereinbefore described,

the chain 17 will be given its automatic essential. ln the present instance of the invention four magazines are indicated, but, of course, the number of magazines may be varied in accordance with the number of lifts that are to be assembled into a heel pile.

The machine frame is provided with guide-ways 19 for a series of feedslides or pushers 20, the function of which is to remove from themagazines a. plurality of heel lifts sufficient in number to constitute a com plete heel pile and deliver the heel lifts onto stepped supports, presently to be descrilgied. The pushers 20 are adjustahly attached by pin and slot connections 21 with. fingers 22 extending from the push bar 2-3. The push bar 23 has connected thereto the guide member 24; which is adapted to slide towards and from the front of the machine in suitable guide-ways 25. The pushers 20, Fig. 7, which are connected to the push bar 23 by the means hereinbefore described, are. arranged in stepped relation, that is, the pusher at the left of the series, F 7, is in a higher plane than the next pusher 200i the series, and so on throughout the entire num ber of pushers. This relative position of the pushers 20 is best effected by the arrangement of the guide-ways 19 in the machine frame. Likewise, the bottom or delivery ends of the magazines are formed in stepped relation in accordance with the stepped relation of the pushers 20, the construction being such that when the pushers are actuated, as will more fully appear, each pusher will take the lowest heel lift from a magazine and simultaneously push or advance the series of heel lifts onto the heel lift supports which will now be described.

I Mounted on the machine frame is a series .of stepped heel lift supports 26 arranged in tion, are preferably horizontal. The term stepped relation is herein used to indicate a series of supports which progressively in crease in height from one end of the series to theother and whose supporting surfaces are in parallel rum-intersecting planes. The difference in he' ht of adjacent stepped supports should be equal at least to the thickness of a heel lift, the construction beingsuch that when lifts are placed upon the stepped supports, the highest lift of the series may be moved or advanced onto the next lift of the-series and then the two advanced to the third lift of the series and so on throughout in order that when the lifts from all of the steps have been assembled, a complete heel pile results.

in order to gather and form the lifts into a heel pile after a series of such lifts have been delivered to the stepped lift supports, the present invention provides an automatic assembling mechanism. In the present instance the sprocket chain 17, already, described, has connected thereto a finger or pusher which is adapted to successively engage and move or advance the heel lifts from one stepped support to another until the entire series has been assembled into a heel pile. Mounted in suitable guides 27, 28, Figs. '1 and 3, and extending substantially parallel to the line of heel lift supports, is a slide 29, Fig. 3, having a vertical slot or guideway 30 in which is mounted the block 31. The block 31 is connected to the sprocket chain 17, as by the pin 32, 3, and as the sprocket chain is moved by the sprocket wheels, as hereinbefore described, the slide 29 will be moved longitudinally to the left. 1, and bacl: to its original position, the block 81 being free to move in the slot 30 of the slide Rising from the slide 29 is the linger 33 which may be connected to the slide by means of the screws or other suitable devices 34, Fig. The upper end of the tinger 3. is extended into alinement with the alined heel supports, as indi rated at 335, Fig. 2, and has adjustably secured thereto the pusher head 36 which, as the sprocket chain and, perforce, the finger 83 is moved to the left, Fig. 1, successively engages the lifts on the stepped lift supports and slides the lifts from the respective supports onto the lifts in the adjacent lower support until the entire series has been assembled into a heel. pile. The head 36 may be connected to the finger by the adjusting bolt 37 which may pass through a slot in the portion of the linger and permit the head 36 to be properly ad justed relative to the other parts. To order that the head 36may act as hereinbefore described, the stepped heel lift supports 26 are longitudinally slotted at 38 and 39 at each side of a central guide rib tO, and'the head 36 is formed with the leg portions 41 which straddle the central rib 4.0 and serve to guide the head 36 as it advances in the line of heel lifts.

The heel lifts that are placed in the mag azines for assembling into heel piles may be of usual character, but in the present in stance of the invention the heel lifts are preferably provided with an adhesive on one surface which is dried before the lifts placed in the magazines and as the lifts are pushed from the magazines for delivery to the stepped sulmorts, the gummed and d ed surface is moistened or pered. T he moistening or tempering action is best car ried into effect by means of a pad which may be of suitable absorptive material, such as felt or the lilrmand be held between the side clamping plates all, best indicated in Figs. 1 and 2. The clamping plates and the enclosed pad may secured in position between the magazines and the stepped heel supports by the screws or other fastenings which preferably pass into a front portion 46 associated with the several magazines.

The pad between the plates at is supplied with the tempering liquid which is preferably water, by means of a pipe 417 connected to asource of supply and having branch connections 48 at intervals with the pad. A valve 49 in the pipe A? serves to regulate the supply of liquid or water to the pad.

Since the heel lift supports are arrange in stepped relation, as described, and the heel lifts themselves are moved from the magazines in stepped relation onto the stepped supports, the lower active edge of the pad 43 is formed with stepped portions 50 which serve to contact with the upper surfaces of the heel lifts as they are moved from the magazines to the stepped supports.

lVhen the heel pile has been assembled, it is to be placed in the heel form and then subjected to the pressing and nailing oper ation. The automatic assembling of the heel lifts from the stepped supports may, of course, be associated with different forms of pressing and nailing machines. ln the present instance the pressmg and nailing mechanism may be substantially the same as that disclosed in United States Letters Patent No. 1,056,720 granted March 18,1913, to Eliphalet A. Tripp, wherein a beam or head constituting one of the presser memhers is moved to and from operative position with relation to the heel form, and the nailing of the heel pile is effected by actuation of the nailing mechanism when the beam or head is brought to its presing position.

i As shown more clearly in Figs. 4 and 5, the head or beam 51 is of the general type of that shown and described in the abovementioned patent and the action of the nailing mechanism iselfected automatically by the frontward movement of the beam or head into the pressing position, as more fully inane-1a describedv in the said patent. The head or beam 51 carries the presser member 52 yieldingly mounted in the head through the instrumentality of the spring 53, and a handle 54: serves as a convenient means for the attendant to more the beam or head into its operative or inoperative position relative to the heel form.

The heel form comprises the bottom plate 55 which is provided with nail driving passages 56 and the fixed side jaw 57 and the movable side jaw 58. The supporting surface of the bottom of the heel form is preferably arranged in the same plane as the lowest heel lift support 26, the construction being such that after the pile of heel lifts has been completed as hereinbefore described, they may be moved as a unit'into the heel form, the movable jaw 58 at such times being open for the reception of the heel pile, as will more fully appear.

Below the bottom of the heel form is the nail block 59, Fig. 4-, with which is associated the driver block 60 having the drivers 61 for driving nails which are delivered to the nail receiving openings in the nail block. Between the nail block and the driver block 60 are the rods 62 which serve to cause movement of the nail block and the driver block to and from driving and nail receiving position in unison. The driver head 63 has the usual reciprocating movement through toggle levers 64. only one of which is shown in the present illustration, but which may be as more fully described in said patent.

Mounted for sliding movement towards and from the front of the machine in suitable bearings 65, are the two slides 66, one each side of the beam or head 51. The slides 66 are provided with the guide-ways 67, Fig. 4, which may be formed by lugs 68 secured to the slides and suitably spaced apart. The guidcovays 6'? are engaged by lugs or rolls 69 carried by the downwardly extending portion of the head 51, the construction being such that as the head or beam 51 is moved frontwardly to operative position relative to the heel form, the slide bars 66 will be correspondingly moved, and, reversely, when the head or beam 51 is moved backwardly, the slide bar 66 will partake of such movement also. Mounted on the slide 66 are the brackets 70. Figs. 4 and 5, which are provided. with the hook portions 71 adapted to complemental hook. portions 72 on the driver block 60 when the latter is lowered from the position of Fig. 5 to that of 4 so that the driver block 66 may partake of the movement of the slide 66, the construction being such that when after a nailing operation the driver block 60 is lowered by the descent of the driver head, the hooks 71 and 72 interengage and on backward movement of the head or beam 51 the slide bar .66 carries the driver block and of engagement with the lugs of the llorton clutch and, as the slide 66 moves frontwardly, which is coincident with the move ment of the beam or head to its operative position, the hunter 112 will move frontwardly and permit the dog 12 to more into engagement with the Horton clutch stop in operative position relative to the heel forn' the construction being such that as the i latch 108 is tripped by trontward movement of the slide 66, the dog 13 will be moved to its inoperative or disengaging position relative to the Horton clutch and the dog 12 will be moved. into its operative or holding position, so that the auton'iatic heel assembling mechanism will remain at rest. When the bean'i or head 51 is moved backwardly to its inoperative position after a pressing and nailing operation, the hunter 112will strike the lug 113 on the dog 12 and remove it from engagement with the lugs of the Horton clutch, thereby starting into operation the automatic heel assembling mechanism. As the assembling mechanism moves in its heel lift asembling path, tie bar 106, presently to be more fully described, will be moved to the left out of engagement with the bell crank 102, with the result that the spring 115 which normally acts upon the sleeve 100 to move it frontwardly, will carry the end 109 of the latch 108 into engagement with the notch 110 of the rod 99, so that on backward movement of the bar 106 after the delivery of a heel. pile to the heel form, the projection 105 will move the belly crank 102 and, perforce, trip the clutch and stop the operation of the automatic assembling mechanism. Thus it will be understood that when a pile of heel lifts is being subjected to the pressing and nailing operation, the automatic heel assembling mechanism is at rest, and when the pressing and nailing operation is completed and the beam or head. 51 is moved to its rearward position, the as sembling mechanism is rendered operative.

The bar 106, hereinbefore referred to, is best shown in Figs. 1, 2 and 3. It is connected to the slide 29, Fig. 2, by suitable means, such as the screw 116, Fig. 3, and is guided in its longitudinal movement in a suitable guide-way 117.

W hen the automatic heel lift assembling mechanism isoperating to successively move the heel hits from their stepped supports and form them into a heel pile and then delivering the formed heel pile to the heel form, it is desirable that thepressing and nailing mechanism be prevented from actuation by the attendant or moved to their operative positions. To this end the bar 106 is moved tansversely of the machine by the heel lift assembling mechanism and 'entends frontwardly of the front end portions of the slide 66 which, being connected to the beam or head. 51, prevents movement of the head or beam to its operative position relative to the heel form while the automatic assembling mechanism is in operation.

When the pile of heel lifts has been subjected to pressure and nailed, it is desirable that the pile of lifts be now ejected from the machine to permit another pile of lifts to be placed intheheel form by the assembling mechanism. To this end the present invention provides an ejecting n'iechanisnji actuated by movement of the beam or head. The beam or head 51 has connected thereto the links 118, Fig. 2, to which is jointed the cross head 119. A through the cross head 119 and has astop 121. The frontward end of the rod 120 is se cured to a lug 122 formed as part of a cross member 123 and a spring 124 is interposed between the cross head 119 and lug 122..

From the cross piece 128 there extends forwardly two side members 125 which travel in the guide-ways 126 in the machine frame at opposite sides of the heel form, as indicatedin Fig. 2. Projecting forwardly from the cross piece 123 is the heel ejector 127, and oppositely disposed thereto is the pad 128 on the front cross piece 129 which isfcarried by the side members 125.

Mounted in bearings formed in the machine frame below the cross piece 123 are the catches 130, Figs. 1 and 5, which are normally held upwardly projected by the springs 131 and in front of the cross piece 123 when the head or beam 51 is in its rearward position. I

lVhen the head or beam 51 is'moved frontwardlyiiito operative position, the spring 12 1 is placed under tension and the cross piece 123 held by the catches 130 from moving frontwardly, as indicated by full lines in Fig. l Vhen the beam or head 51 is given its downward movement to compress the heel pile, lugs 132 on the side of the beam members are moved downwardly into engagement with. lugs 133 carried by the catches130' and depress the catches, thereby freeing the ejector to the expansive action of the spring 124, so that when the head is moved. upwardly and pressure removed from the now compressed and nailed heel lifts, the spring 124 asserts itself and throws the heel forwardly where it drops. through'the' opening 134: formed on a 'fro ntwardly projecting portion of the machine frame, as indicated in Figs. 2 and Afterthe compressed and nailed heel pile has been ejected, and the head or beam 51 is moved to its rearward posi-' rod 120 extends loosely tion, the swinging jaw 58 of the heel form opens to permit the bodily movement of another heel pile into the .t'orrn.
